Hi Paleopals,
Gluten level in grain is dependent on the climate it is grown in. The
colder the higher the gluten. If the climate gets hot enough it won't grow
at all. This is why in hot parts of the world what bread they have is flat.
Not enough gluten content for leavened bread. And in super hot places, like
Madras India, there is no wheat at all.
There are a lot of very good articles about how grains were forced to grow
in climates that cannot usually support grain growing-like Canada. The
higher gluten content ensures survival in northern climes.
Here is one that has been mentioned before. Scroll down to 'Control of Grain':

Search 'Rockerfeller and grains' and you will find a lot of information.
Paleobest,
